Pop them between meals or with your protein. Cooper will tell you guys why you should be adding leucine to your protein

They don't need me to. The research of Layne Norton, lead PhD in the field of muscle protein synthesis and top natural BBer, has shown that the L-leucine content of a meal determines the amplitude and duration of the muscle protein synthesis spike, among other things.

Consider this a cheaper, convenient way to do Layne's protocol. No need to mix up BCAA shakes 5 times a day...just pop 3 tabs (the product comes with a LOT of tabs, so no worries here) and you're good to go.

Use it when fasted preworkout, between meals, with meals...the convenience is key

Abstract
The effects of supplementation of the leucine metabolite beta-hydroxy-beta-methylbutyrate (HMB) were examined in a resistance training study. Thirty-nine men and 36 women between the ages of 20-40 y were randomized to either a placebo (P) supplemented or HMB supplemented (3.0 g HMB/d) group in two gender cohorts. All subjects trained three times per week for 4 wk. In the HMB group, plasma creatine phosphokinase levels tended to be suppressed compared to the placebo group following the 4 wk of resistance training (HMB:174. 4 +/- 26.8 to 173.5 +/- 17.0 U/L; P:155.0 +/- 20.8 to 195.2 +/- 23.5 U/L). There were no significant differences in strength gains based on prior training status or gender with HMB supplementation. The HMB group had a greater increase in upper body strength than the placebo group (HMB:7.5 +/- 0.6 kg; P:5.2 +/- 0.6 kg; P = 0.008). The HMB groups increased fat-free weight by 1.4 +/- 0.2 kg and decreased percent fat by 1.1% +/- 0.2% while the placebo groups increased fat-free weight by 0.9 +/- 0.2 kg and decreased percent fat by 0.5% +/- 0.2% (fat-free weight P = 0.08, percent fat P = 0.08, HMB compared to placebo). In summary, this is the first short-term study to investigate the roles of gender and training status on the effects of HMB supplementation on strength and body composition. This study showed, regardless of gender or training status, HMB may increase upper body strength and minimize muscle damage when combined with an exercise program.

I would love to see a few things sometime down the road.
First would be a nootropic blend. Not one necessarily intended to be used preworkout, but whenever someone decides he/she could use a bit of a cognitive boost.
Second would be a blend of adaptogens. It seems that this class of supplements is growing increasingly popular, and for good reason! It'd be awesome to have an affordable product that includes some of the most popular ones.
Finally, a nice little t-boosting product would be cool too. I'm sure you guys would formulate an effective blend of some high quality extracts. That would sell really well too I'm sure!
